Abstract (en)

[origin: EP3982178A1] This optical fiber fusion splicer is a device for fusion splicing, by an arc discharge, a pair or a plurality of pairs of optical fibers arranged so that end surfaces thereof face each other. This device includes a pair of electrodes, an optical fiber arrangement part, and a control part. The pair of electrodes generates the arc discharge. The optical fiber arrangement portion positions the pair or the plurality of pairs of optical fibers between a pair of electrodes. The control portion controls a voltage applied to the pair of electrodes. The control portion generates a first discharge between the pair of electrodes, stops the first discharge between the pair of electrodes, and then generates an arc discharge between the pair of electrodes to fusion-splice the pair or the plurality of pairs of optical fibers to each other. A discharge time of the first discharge is 200 milliseconds or less. A time from stopping the first discharge to starting the arc discharge is 100 milliseconds or less.
